Abstract
Abstract Infrared light from an object directed into a thermal imaging television camera by a lens is passed through an angularly mounted rotating plate to impart orbital motion to the image received upon the image plane of the camera. A variable speed drive is operatively connected to the plate by an elastomeric belt to rotate the plate with a minimum of mechanical vibration. The operator can adjust the speed of the plate's rotation to improve the clarity of the particular scene being televised.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
115 words
An orbiter for pyroelectric focusing devices having an image plane comprising means for focusing infrared radiation upon the image plane; a pyroelectric target positioned in the image plane for showing an image of the focused radiation; a plate, transparent to infrared radiation, mounted in front of the image plane, said plate having parallel inclined entry and exits faces; a rotatable mounting means for said plated disposed normal to the optical axis of the focusing device; means to rotate the mounting means about the optical axis; an adjustable speed control for the said rotating means; and an elastomer belt driven by the rotating means and operatively connected to the mounting means for turning said mounting means.
Claim 2
Dependent Claim
115 words
